SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent N o. 792,595, dated June 20, 1905.

Application filed October 25, 1904. Serial No. 229,898.

To all whom, 7115 mmf/y oon/cern,.-

Be it known that I, CHARLES L. HOLLAND, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Sash-Fasteners, of which the following is a specification.

This invention relates to that class of sashfasteners which are adapted to hold the upper and lower sashes in a closed position or to prevent the upper sash when lowered to a limited extent from being lowered still farther from the outside or the lower sash when raised to a limited extent from being raised still fartherfrom the outside, so that the sp'ace between the upper sash and the head of the sash-frame or between the lower sash and the sill cannotbe enlarged from the outside unless such space is sufficiently great to allow the sash-fastener itself to be reached from the outside; and the improvement comprises a plate provided at its opposite ends with means for engaging the inner face of one of the stiles of the upper sash and the outer face of the corresponding inside bead next the upper side of the topor meeting rail of the lower sash, said plate being further provided with a recess or space for the accommodation of the cord or chain of the lower sash and being preferably recessed to accommodate the parting-bead.

The nature of the invention is fully described in'detail below and illustrated in the accompanying drawings, in which- Figure l is a perspective view showing portions of a sash-frame and upper and lower sashes and illustrating my invention in position with the sashes closed. Fig. 2 is a vertical section taken transversely through the meeting-rails of the sashes with the upper sash lowered and my device in position. Fig. 3 is a view in elevation of my improved sash-fastener. Fig. 4 is a section taken on line 4 4, Fig. 3.

Similar letters of reference indicate corresponding parts.

a represents the inside bead, b the outside bead, c the parting-bead, and el the amb, of the sash-frame or window-casing. e represents the top or meeting rail of the lower and size to accommodate the sash, f the lower or meeting rail of the upper sash, and g the stile of the upper sash. /L is the cord of the lower sash. All these parts are constructed in the ordinary and wellknown manner, a chain being often used in place of the cord 7L.

My improved device consists of a strong and sufficiently thick plate 7c, preferably metallic and flat. The opposite ends Z and m of this plate are provided with engaging teeth or prongs, a'nd the toothed end l is provided with a notch n of suitable shape to avoid the parting-bead when the device is in position. T he opposite sides of the plate are preferably plain and parallel, and the side in which the notch n is formed is provided with a recess p, preferably of the curved shape shown, said recess being connected by a passage s with that edge of the plate and being of the shape pulley cord or chain of the lower sash.

Vhen the sashes are to be locked together in a closed position, the plate is inserted between the stile g and the inside bead a, slipped around the cord 71 and laid diagonally with. its lower end m on the upper rail e of the lower sash and against the outer face of the inside bead a, its upper end l lying against the inner face of the stile g of the upper sash, the device being in the diagonal position indicated in Fig. 1, in which the cord extends through the recess p, and the notch n avoids the parting -bead c. Should any one attempt to raise the lower sash or lower the upper sash from the outside, the teeth at the end Z Would be jammed into the stile g and those at the end m would be forced into the bead a or between said bead and the rail e, and the sashes would remain closed and locked. Should the device be applied when the upper sashis lowered for a short distance or the lower sash raised for a short distance, as illustrated in Fig. 2, the plate Would assume exactly the same position with relation to the outer face of the bead a, the inner face of the stile n, the top of the rail e, the cord, and the parting-bead c. It would then be impossible for a person from the outside to enlarge the space left open by lowering the upper sash or by raising the lower sash. All that could be accomplished from the outside would be to close one of the sashes. An attempt to widen the opening would simply cause the teeth to dig more :firmly into the stile g and the bead a or to crowd the lower teeth between the bead a and the rail e.

Of course the plate should be of the proper length to enable it to assume a suitable angle, as too acute an angle might allow the teeth or spurs to slip.

The shape and size of the notch 'a and the recess p may be varied as desired, provided they are large enough and of proper shape to receive the bead e and the rope or chain 7L.

IIaving thus fully described my invention7 what I claim, and desire to secure by Letters Patent, is-

l. The herein-described improved sashfastener, comprising the plate 7c of suitable length to rest in a diagonal position on the upper surface of the top or meeting rail of the lower sash between the inside bead of the window-frame and the stile of the upper sash, said plate being form ed at its upper end with the notch n -for the accommodation of the parting-bead7 and being provided at both ends with means for engaging the surfaces of said stile and inside bead, for the purpose set forth.

2. The herein-described improved sashfastener, comprising the plate 7c of suitable length to rest in a diagonal position on the upper surface of the top or meeting rail of the lower sash between the inside bead of the window-frame and the stile of the upper sash, said plate being provided with the recess p connecting with the rear edge of the plate for the accommodation of the pulley cord or chain of the lower sash, and at both ends with means for engaging the surfaces of said stile and inside bead, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES L. HOLLAND.
